I can't quite decide whether this is the worst idea ever, or the best. Picture the situation -- you bought a digital version of Diablo III, but deep in your heart you regret the decision. Not because of the game itself, but as a result of the fact you don't have a Diablo III box! Fret not! Your prayers have been answered! If you head to KenGamer you can actually buy the Diablo III packaging for two dollars!
Yes, this is correct. You can actually buy all of the standard Diablo III packaging -- including the guest passes -- for two bucks. It contains absolutely everything except the CD Key.
Crazy. But yeah, go nuts everyone!
